As a subgroup within the Esprit Working Group 21108, Integration in Manufacturing and Beyond (IiMB), the authors are concerned with the management of product related data and knowledge in the extended enterprise considering the paradigm of the learning organisation. The focus of the work is on concepts, approaches and methods for capture, maintenance, management and use of data and knowledge ab...

With the rapid development of economy and the increase of population, we are facing the stern challenge of lack of resources and environment pollution. Through the recycling of resources we can reduce the exploitation of native resources and save energy. At present, the level of recycling resources in Nanning city is quite low, as do the utilization rate of recovery. The recyclable resource log...

Materials are a strategic resource and the increasing prices for metals call for an optimized materials use. The prices for materials due to demands, growing faster than the production of virgin material, have put recycling in focus. The mindset “material hygiene” is a pedagogical concept aimed at managing compromises necessary to optimize materials use in products. Consideration to the entire ...

Escherichia coli, and presumably most other gram-negative bacteria, possesses an efficient protein machinery for recycling its peptidoglycan during cell growth. The major recycled peptidoglycan product is N-acetylglucosamine-1,6-anhydro-N-acetylmuramic acid-tetrapeptide. Its uptake from the periplasm into the cytoplasm is carried out via the AmpG protein, an intrinsic membrane protein. In gram-...

The reuse and recycling of critical raw materials is limited, as waste electrical electronic focuses on base precious metals, device component in its infancy. To help to address this issue paper provides the conceptual design a Digital Product Passport based circular supply management system. enable recovery at material levels for recycling. works include an assessment existing information need...

Over 30 million ton of poly(ethylene terephthalate) (PET) is produced each year and no more than 60% all PET bottles are reclaimed for recycling due to material property deteriorations during the mechanical process. Herein, a sustainable approach proposed produce redox-active nanoparticles via chemical upcycling waste application in energy storage. Redox-active sizes lower 100 nm were prepared ...

New government policies aim at the closure of material flows as part of Integrated Chain Management (ICMl. One of the main implementation instruments is extended producer responsibility. which makes Original Equipment Manufacturers (OEMs) formally responsible for. take-back, recovery and reuse of discarded products. One of the key problems for OEMs is to determine to what extent return products...
